He wrote:"And Medvedev needs to take the rest of the year off"The loss marks another premature exit from a major tournament this year.

During the tiebreak, a fan unexpectedly entered the court, causing a small disruption. Because of this, chair umpire Greg Allensworth granted a first serve to Benjamin Bonzi. This decision didn't sit well with Medvedev as he made his frustration known to the umpire. He called out the chair umpire, saying:"Are you a man? Are you a man? why are you shaking? What’s wrong huh? He wants to go home guys. He doesn't like to be here. He gets paid by the match not by the hour."He also referenced Reilly Opelka, calling Allensworth the worst umpire on the tour to further criticise the chair umpire. Some fans in the crowd got behind Daniil Medvedev as well in the process. However, in the end, his comeback went in vain.
